Optical computing or photonic computing uses light waves produced by lasers or incoherent sources for data processing, data storage or data communication for computing.For decades, photons have shown promise to enable a higher bandwidth than the electrons used in conventional computers (see optical fibers).
Disk storage (also sometimes called drive storage) is a data storage mechanism based on a rotating disk. The recording employs various electronic, magnetic, optical, or mechanical changes to the disk's surface layer.
As a consequence of rapid development of electronic computers, capability for integration of existing input, output, and storage devices was a determinant factor in their adoption. [8]
A photophone receiver and headset, one half of Bell and Tainter's optical telecommunication system of 1880. Optical communications, in various forms, have been used for thousands of years.
An electro-optic phase modulator for free-space beams An optical intensity modulator for optical telecommunications. An electro-optic modulator (EOM) is an optical device in which a signal-controlled element exhibiting an electro-optic effect is used to modulate a beam of light.
A bundle of optical fibers A TOSLINK fiber optic audio cable with red light shone in one end. An optical fiber, or optical fibre, is a flexible glass or plastic fiber that can transmit light [a] from one end to the other.
Phase shift through a beam splitter with a dielectric coating. Beam splitters are sometimes used to recombine beams of light, as in a Mach–Zehnder interferometer.In this case there are two incoming beams, and potentially two outgoing beams.
